Module::Math::Depends - Convenience object for manipulating module dependencies

This is a small convenience module created originally as part of Module::Inspector but released seperately, in the hope that people might find it useful in other contexts.

  my $deps = Module::Math::Depends->new;

Creates a new, empty, dependency set.

  my $deps = Module::Math::Depends->from_hash( \%modules );

Creates a new dependency set from a raw hashref of modules names and versions.

  $deps->add_module( 'My::Module' => '1.23' );

Adds a single module dependency to the set.

Returns true, or dies on error.

  $my_deps->merge( $your_deps );

The merge method takes another dependency set and merges it into the current one, taking the highest version where both sets contain a module.

Returns true or dies on error.

  print $depends->as_string;

Converts the dependency set to a simple printable string.

This module is stored in an Open Repository at the following address.

http://svn.ali.as/cpan/trunk/Module-Math-Depends

Write access to the repository is made available automatically to any published CPAN author, and to most other volunteers on request.

If you are able to submit your bug report in the form of new (failing) unit tests, or can apply your fix directly instead of submitting a patch, you are strongly encouraged to do so as the author currently maintains over 100 modules and it can take some time to deal with non-Critcal bug reports or patches.

This will guarentee that your issue will be addressed in the next release of the module.

If you cannot provide a direct test or fix, or don't have time to do so, then regular bug reports are still accepted and appreciated via the CPAN bug tracker.

For other issues, for commercial enhancement or support, or to have your write access enabled for the repository, contact the author at the email address above.
